Many of us remember being in awe(敬畏) when we saw cloned dinosaurs running wild in the film Jurassic Park. And the idea of using technology to revive(恢复) extinct species has long fascinated not only writers and directors, but scientists as well.

    According to The Telegraph, woolly mammoths(长毛猛犸象), which featured in the popular Ice Age animated movie series, “may walk the earth once more” now that scientists have taken another step toward realizing a long-held dream—recreating their DNA.

    Mammoths became extinct around 10,000 years ago. However, since the discovery of near-perfect preserved remains in Arctic permafrost(北极冻土带) in May 2013, a variety of research studies have been carried out since.

    Geneticists from Harvard University analyzed DNA from the remains, looking for genes which separated mammoths from elephants, such as hairiness and ear size. They then used the results to reproduce exact copies of 14 mammoth genes. “It is the first time that mammoth genes have been alive—although so far it has only been done in the lab,” George Church, lead researcher of the project, told the Sunday Times.

    Church then used a new technique which allows scientists to edit DNA carefully, replacing sections of elephant DNA with the mammoth genes. So “we now have functioning elephant cells with mammoth DNA in them,” he said.

    However, Church ruled out the possibility of bringing the mammoths back to life via cloning from frozen remains. He said he “preferred to focus on rebuilding the full mammoth genome(基因组) by analyzing DNA from preserved remains and putting it into the cells of its closest living relative – the Asian elephant,” reported The Telegraph.

    Church argued that the return of the woolly mammoth—or rather, the return of something very similar—could help bring back fragile(脆弱的) ecosystems. However, some scientists believe that bringing back the mammoth would be unethical.

    Professor Alex Greenwood, an expert on ancient DNA, said: “We may face the extinction of African and Asian elephants. Why bring back another elephant from extinction when we cannot even keep the ones that are not extinct around?” he told the Sunday Times. “What is the message? We can be as irresponsible with the environment as we want. Then we'll just clone things back?”

    “Money would be better spent focusing on conserving what we do have than spending it on an animal that has been extinct for thousands of years,” he said.

    Although problems are a part of our lives, it certainly doesn't mean that we let them rule our lives forever. One day or the other, you'll have to stand up and say – problem, I don't want you in my life.

    {#blank#}1{#/blank#} Problems with friends, parents, girlfriends, husbands, and children – the list goes on. Apart from these, the inner conflicts within ourselves work, too. These keep adding to our problems. Problems come in different shapes and colors and feelings.

    But good news is that all problems can be dealt with. Now read on to know how to solve your problems.

    Talk, it really helps. What most of us think is that our problem can be understood only by us and that no talking is going to help. {#blank#}2{#/blank#} Talking helps you move on and let go.

    Write your problems. {#blank#}3{#/blank#}When you write down your problems, you are setting free all the tension from your system. You can try throwing away the paper on which you wrote your problems. By doing this, imagine yourself throwing away the problems from your life.

    Don't lose faith and hope. No matter what you lose in life, don't lose faith and hope. Even if you lose all your money, family… you should still have faith. {#blank#}4{#/blank#}

    Your problems aren't the worst. No matter what problem you get in life, there're another one million people whose problems are huger than yours. {#blank#}5{#/blank#} Your problems might just seem big and worse, but in reality they can be removed.

    Go about and solve your problems because every problem, however big or small, always has a way out.

A. But the truth is that when you talk about it, you're setting free the negative energies that have been gathering within you.

B. When we have a problem, a pressing, critical, urgent, life-threatening problem, how do we try and solve it?

C. Tell yourself: when they can deal with them, why can't I?

D. Of course, we've been fighting troubles ever since we were born.

E. We can often overcome the problem and achieve the goal by making a direct attack.

F. Having a personal diary can also be of huge help if you don't want a real person to talk with.

G. With faith and hope, you can rebuild everything that you lose.

    Customers who come into the Waffle House recognize server Evoni Williams, a soft-spoken 18-year-old from Texas City. It all started with a Facebook post. On the morning of March 3, Laura Wolf was eating breakfast at the Waffle House in La Marque when she overheard an older man, who reminded her of her late father, tell Williams he had trouble with his hands. The man, later identified as regular customer Adrien Charpentier, had an oxygen tank nearby and needed help cutting up his food. “Without hesitation,” Wolf wrote, Williams “took his plate and began cutting up his ham.”

    Impressed, Wolf posted the moment on her Facebook page to share the warmth and kindness with all. The following day, Williams's Facebook notification（关注）began to light up. Her friends saw Wolf's post and tracked her in it.

    Williams had no idea that someone took a photo that morning. The diner was so busy that a line extended outside the door. She said helping Charpentier was reflexive. She has been working at Waffle House since last June to save for college, and this, she figured, was just the right thing to do. “I would want someone to help my grandmother or grandfather,” Williams said.

    The post began to make its rounds in La Marque and eventually landed in front of the city's mayor, Bobby Hocking. He decided to declare March 8 as Williams's day, and also received an email from Texas Southern University President Austin A.Lane, asking if the school could present Williams with a scholarship.

    Williams still works at Waffle House five days a week and plans to do so until she starts classes in the fall at Houston-based Texas Southern. Wolf said Williams does not have a car to get to classes, but some people have offered to start a GoFundMe page for her, proving that a moment of a kindness can change a life.

    If you have a chance to take a walk in a park, look carefully at the people walking their dogs. You'll probably find friendly-looking people with friendly dogs; quiet people with quiet dogs; large men with oversized dogs and long-haired women with long-eared dogs. As you've probably noticed, dogs and their owners look alike. Have you ever wondered why?

    These similarities are so common that researchers have tried to explain them. There are two theories (理论): the convergence (趋同) theory and the selection theory. The convergence theory says that as the owner and the dog spend more time together, they influence each other to the point where they grow similar. In other words, they “converge.” The selection theory, on the other hand, says that owners are interested in dogs that look like them, so they choose those dogs as pets.

    Recently, researchers at the University of California decided to test the two theories by taking pictures of 45 dogs separately from their owners. Then they asked some students to match the dogs' photos with their owners. The students were quite successful with purebred (纯种的) dogs: they correctly matched 16 out of 25 with their owners. However, they had almost no success connecting mixed-breed (杂交的) dogs with their owners. When owners select a purebred dog, they can easily predict (预测) what it will look like later. But that is not true with mixed-breed dogs because it's hard to predict what a mixed-breed dog will look like when it grows up. And since it was the purebreds not the mixed-breeds that looked like their owners, the research seems to prove the “selection theory”.

    But one bit of warning. Although many people look like their dogs, not all dog owners enjoy having the similarity pointed out to them. So, even if the similarity is amazing, don't go up to a stranger and say, “Wow, you look just like your dog!”
